2. Collect the chopped spinach in a bowl and add corn kernels, 2 tablespoon sandwich spread and mix well.
3. Take a slice of bread, spread 1 tablespoon of sandwich spread all over and top it with the spinach mix. Cover it with another slice of bread. Keep aside and make another sandwich from the rest of the two slices.
4. Heat a grill pan or sandwich maker with butter. Place the prepared sandwich and grill from both sides until crisp and golden in colour.
5. Transfer on a serving plate, cut into two diagonally and serve hot.
